The invention relates to .a covering for walls, floors, etc.,constituting a simulation of tile or the like, and it may representglazed or unglazed tile, ceramic tile, glazed or un- 5 glazed brick,mosaic, stone, marble, terra cotta, etc., and hence, even though suchexpressions as tiles, tile simulations, etc., maybe hereinafter used, itis to be understood that l am not restricted to the simula- 10 tion ofactual tiles.

The invention further relates to ay covering in which plastic-receivingand retaining grooves areprovided between the tile simulations to befilled with pointing material after 15 application of the covering, thusnot only enhancing.appearance, but hiding all nails which may be usedinY attaching the covering, as well as obscuring any seams.

It is one object of the invention to provide the plastic-receiving andretaining` grooves of suoli forni that they are much wider near theirinner closed sides, than at their open sides. Thus, not only will. theplastic pointing material be effectively held in place withi in thegrooves, but a much larger body 'of such pointing material may be used,thereby retarding` the drying out of such pointing material andincreasing its strength accordingly.

.A further object of the invention is to provide a covering of rigidnature, in which the tile., simulations mayV be` advantageously formedas separate units from a rigid backboard and cementedy or otherwisesecured to this board atA the factory. Under this method.v the shape,color or shade and other characteristics of thesimulations, Vmay bevaried on the same backing board producing` effects obtainable in noother manner except with actual ceramic tiles. TheV rigidity ofstructure permits the device to be secured directly to spaced studs`rafters or other spaced members without the necessity of any continuousbacking surface. However, it iuav be cemented against a surface such asa. floor or a plaster-covered or other wall if desired, in whichconnection, a further aim is to provide novel means whereby any surplusof cement or the like used for securing the covering to the Surface, maybe received in a multiplicity of sockets formed in the reverse side ofthe covering, the cement or thelike so received, serving also toestablish effective keys between the covering and the cement.

lith the foregoing in view, the invention resides in the novel subjectmatter hereinafter described and claimed, description being accomplishedby reference to the accompanying drawings.

Fig. 1 is an elevation showing a portion of the wall covering secured tostuds.

Fig. 2 is an enlarged horizontal sectional view online 2-.-2 of Fig. l.

F 3 is a similar view on line 3 3 of Fig.

1 but showing the pointing material in place.

F 4 isa view similar to Fig. 3 but showing` a modified form ofconstruction in which the back of the covering is formed with sockets.

Fig. o is a fiagmentaiy rear elevation of the construction shown inFig.1t.

ln the drawings above brieflyV described,

the numeral 6 denotesl a substantially rigid backing sheet or boardformed of any suitable composition. Secured upon the Viront side of thisbacking sheet oi' board, vfor y instance by a layer of appropriatecement 7, are the tile simulations 8 which are also of appropriatecomposition.

The edges 9 of the simulations S, are spaced apart to provide plasticreceiving and retaining grooves l() for an appropriate pointingmaterial, and said edges are so shaped (preferably beveled) .as to givea greater width to the inner closed sides of the grooves, than to theirouter open sides. .These grooves are preferably given a-dove-tailformation which insures that the 'plastic pointing material 11 Shall notfall therefrom.

Cil

also insures that a sufficient quantity of the pointing material shallbe received in thel grooves, to prevent rapid drying and wealteningincident thereto. Moreover, the beveled edges of the tiles have amanufacturing advantage, in that they permit easy removal of these tilesfrom the moulds, if such moulds be used in constructing said tiles.

TWhen the covering is to be mounted by nailing` it in place, forinstance against studs S, the nails N are driven through the backingsheet or board 6, so that their heads will be confined within thegrooves 10. rihus, when the pointing material 11 is later disposed inthese grooves, the nail heads will be hidden. Similarly, all seams arelocated so that they will be covered by the pointing material. Thecovering is completely manufactured in sheets of desired sizes, may beconveniently sawed or otherwise cut for fittingv as required, and aftersecuring in place, is pointed up, that is the grooves 10 are filled withthe pointing` material 11, giving an excellent representation of actualtile.

For use with the covering, appropriate liners, bands, ornamentalfriezes, caps, moldings, bases, etc., all constructed in similar mannerand in assembled units, may be provided.

Vhen the covering is manufactured primarily to be secured against a flatsurface such as a plastered or other wall, instead of being nailed tostuds or the like, the construction shown in Figs. 4 and 5, ispreferably followed. This construction is ident-ical with that abovedescribed, with the exception that the back board 6 has a number ofsmall openings 12 formed entirely through it. The outer ends of theseopenings receive part of the cement 7, by means of which the simulations8 are secured to the backing board or sheet 6, as denoted at 7a, thusgiving an unusually strong anchorage for this cement. The inner portionsof the openings 12 rereceive portions 13 of a viscous or other cement 14which is used to secure the covering against a wall, floor or othersurface 15. Not only do the portions 13 form effective keys between thecement or the like 14 and the covering, but as the openings 12 are veryclosely spaced, they receive any excess of the material 14 which may beapplied over one area or another and hence permit the finished wall tobe free from projecting and depressed portions.

Obviously the covering of Figs. 4 and 5, maybe nailed in place ifdesired, the nails being driven in the grooves between the tiles 8 asbefore described.

Preferably, the backing board or sheet 6 is of about one-eighth inch inthickness, and the same is true of the tile simulations 8. The openings12 may well be of one-eighth inch diameter and spaced apart threequarters of an inch.

From the construction shown and described, eXcellent results may beobtained and the details which l have herein disclosed are preferablyfollowed. However, within the scope of the invention as claimed,variations may be made. For instance, although the back board or sheet 6is preferably rigid, it will be obvious that the grooves 10, shaped asdescribed, would possess the same advantages even if said back board orsheet were of more or less flexible nature. Similarly, the sockets oropenings 12 would possess virtually the same functions if the backingboard or sheet 6 were of a nature other than rigid. Hence, 1 wish to beconsidered as contemplating such variations, within the scope of theclaimed invention. llloreover, l wish it understood that l am notrestricted to specific materials, dimensions, ornamentation, etc.

l claim:

1. A covering comprising a backing sheet, and tile simulations separatefrom each other, separate from said backing sheet and all permanentlvsecured to said backing sheet before application of the covering to abuilding structure,l said simultations being spaced apart bothlongitudinally and transversely to provide both longitudinal andtransverse plastic-receiving-and-retaining and nail-receiving grooves,said tile simulations having all of their edges beveled to impartgreater width to said grooves at their closed sides than at their opensides and to allow easy removal of said simulations from moulds if theybe so formed, said permanently secured tile simulations and groovesoccupying the entire area of said backing sheet.

2. ln a covering of the type adapted for cementing against the surfaceof a support, arvperforated backing of such thickness that itsperforations possess appreciable front-t0- rear lengths, and tilesimulations cemented upon the front face of said perforated baclring andhaving their edges spaced apart to provide grooves adapted to receivepointing material after complete cementing of the covering to thesupport, said simulations and perforations being so located that none ofsaid perforations open into said grooves, whereby although the frontends of said perforations may receive key portions of the cement whichattaches the simulations to the backing, and the rear ends of saidperforations may receive key portions of the cement used for attaching`the backing to the support, none of said cement can enter said groovesto interfere with introduction of the pointing material into the latter.

In testimony whereof I have hereunto affixed my signature.
